Transformer-based Hypernetwork (FTHNet)
FTHNet employs a Transformer Backbone for efficient feature extraction, a Distortion Perception Network to capture various degradation types, and a Parameter Hypernetwork to dynamically generate weights and biases. This innovative architecture enables continuous quality score prediction, moving beyond traditional classification for more nuanced assessment.
Key components: Transformer Backbone (Basic Transformer Blocks), Distortion Perception Network, Parameter Hypernetwork, and Target Network.
Fundus Quality Score (FQS) Dataset
The FQS dataset is a new benchmark featuring 2,246 fundus images, each with a continuous Mean Opinion Score (MOS) from 0 to 100 and three-level quality categories (Good, Usable, Reject). Collected from clinical practice, it covers diverse degradation types and is publicly available to foster research.
Annotation: MOS determined by weighted averaging from six ophthalmologists, ensuring consistency and clinical relevance.
Superior Performance
FTHNet-L achieved a Pearson Linear Correlation Coefficient (PLCC) of 0.9442 and a Spearman Rank Correlation Coefficient (SRCC) of 0.9358, significantly outperforming state-of-the-art methods. The lightweight FTHNet-S model also demonstrates strong results with fewer parameters, highlighting its efficiency.
Metrics: RMSE, PLCC, and SRCC are used to evaluate the model's prediction accuracy and monotonicity.
Seamless Clinical Integration
With an inference time of just 44.45 ms for FTHNet-S, the model is suitable for real-time deployment in automated diagnosis systems. This enables rapid quality control during image acquisition and enhances the reliability of subsequent pathology information provided to ophthalmologists.
Impact: Boosts diagnostic speed, reduces redundant image captures, and improves overall medical record quality.
0.9442
Peak PLCC achieved by FTHNet-L
The Pearson Linear Correlation Coefficient (PLCC) is a key metric for regression models, indicating a strong linear relationship between predicted and ground-truth scores. FTHNet-L's high PLCC demonstrates its exceptional accuracy in continuous quality assessment.
